In reference to the bold. I'm very surprised by how many people would not call 911 at finding their door broken in. Even if your family wasn't home and there was no bad guy in the house it's still a crime scene until proven otherwise. Why wait? You can always call them back and say, "Hey, sorry. I just found out it was an accident."
Okay, the OP said he was concerned enough to draw his weapon while anticipating trouble. At this point, call 911 if you are that concerned! I'm not even sure I would have called 911 at this point. However, everything is silent, so you don't know if family is home or not. So, based on the OP scenario, he obviously unlocked the door and entered.
Well, then the choices suck!!! LOL
Still nothing is indicating any trouble as he walks thru the house (read "clear" if you must), until he gets to the bedroom and the door is closed. He "must" reach out and attempt to open the door in order to determine it was locked. Once he determined the door was locked, he now calls out and then listens for an answer. He then hears a low whimper only.
Now, at THIS point I think any rational individual will either call 911 and call out again, or call out again, or, as in the OP scenario, "force the door"...
The picture you are now presented with is some or all of family held hostage in the bedroom by the home invader. The invader is "holding your youngest child at gunpoint (specifically pointing at the child's head).
WHAT WILL YOU DO is the question the OP had based on the scenario. In an ideal situation, we might all hope to react as Lima or Tacman BUT that's not what the OP asked. The decisions have ALREADY BEEN MADE up to the point of facing the invader with a gun pointed at your youngest child's head. WHAT WILL YOU DO?
The OP gave us 4 choices...Properly clearing the house wasn't one of them...Calling 911 and waiting for a response wasn't one of them...etc etc We have 4 potential responses to choose from and I assume he wanted to know why you made the choice you made..
